General Motors is showcasing their PowerWall which helps designers and engineers develop vehicles faster than ever before.

Essentially a 240 square foot (22.3 square meter) solid glass screen, the PowerWall is powered by eight computers and two Christie Spyder X20 video processors. Both 2D and 3D content can be shown on the screen thanks to two Christie Mirage 4K25 DLP 3D projectors.

While this doesn't sound terribly exciting, GM says the system allows designers and engineers to compare different parts without the need for creating expensive physical prototypes.

The company also says the screen played a major role in the development of the 2015 Chevrolet Colorado as engineers noticed the truck's chrome assist steps could reflect drain holes located underneath the cab. As a result, the side steps were equipped with black treads to solve the issue more than a year before a physical prototype was available.
